@dc42 Ah, gotcha. I hadn't thought of doing it that way probably because all of my other Eclipse based projects (I've got about 25 of them) use the Eclipse builder to just run make or ninja, etc. on existing build scripts. Since 3.3 is EOL and you're planning to move 3.4 to gcc 12.2 anyway, it'snot really an issue any more. If it becomes one for 3.6 or later versions I can easily do the separate workspace thing as you do.
Thanks!
